Application filed m '12, 1925. Serial No.29,801.

This invention relates to box filling ma chines, and more especially tomechanism whereby box trays are supplied to'the successiv'ef holders ofan intermittently travel-' ing carrier by means of which the trays areconveyed to the various stations of the ifilling machine.

The ob ect of my invention is to provide sim le and eficient mechanismwhereb the boxes and feed them along the horizontal portion'of thetrough,- and whereof the other member is operative with the first-namedmember and is arranged to engage the successive leading boxes and swingthem through the curved portion of the trough and to position fordelivery into the succeeding holders of the carrier; as will behereinafter described and claimed.

In the drawings Figure 1 is a plan of a portion of a match box fillingmachine embodying any invention.

Fig. 2 is a longitudinal vertical section, as on the line 22 of Fig. 1.

is a transverse vertical section, enlarged, as on the line 33 of Fig.1.

Fig. 1 is a perspective view of the two feed members and theirconnections, showing a section of the trough, box trays therein and then'iembersengaged with the adjacent trays. 1

Referring to the drawings, 5 designates a portion of the bed or table ofa filling machine, and 6 a portion of the upper run of theintermittentlymovable tray carrier of the machine, which carriercomprises an endless chain of holders 7 constructed and arranged toreceive the trays, 8, in succession and convey them along the bed ortable to a station where the trays are filled with matches or otherarticles.

Arranged on the bed or table and laterally of the carrier, is a trayguiding trough into the receiving end of which the trays in end to endrelation are advanced from a suitable source of supply. This troughcomprises a main body portion 9 extending parallel with the upper run ofthe carrier and Fig.5

terminating in a curved delivery portion 10 of suitable radius andlength leading'to or adjacentthe horizontal path-of the tray holders.

Spaced from and parallel with-the Outer side of thetrough body 9 is arail 11 which in conjunction with the outer side of the trough slidablysupports a plate 12 having at one end a bracket member 13 whichoverhangs the'receiving portionof the trough. The plate is provided onits under side with a guide rib 14 slidably fitted in the'wayor spaceformed between the trough and the rail 11. On the bracket member ispivoted a push pawl 15 which'normally gravitates into the underlyingtraywithin the trough:

The plate 12 is flexibly connected by means-of a rod 16 with one end ofan oscillatory radius arn'i17'which' overhangs the juncture of the mainbody of the troughwith'the curved end portion 10, and is movable in anarc substantially concentric with that of the said end portion. Thisplate pivotally supports apush pawl 18 which normally gravitates traywithin the curved portion. Hence the two pawls are simultaneouslyactuated by the operation of the arm 17. This arm is secured to theupper end of a vertical shaft 19 journaled in a bearing 20 supported onand depending below the table. Fixedon the lower end of the shaft is asector gear 21in mesh with a similar gear 22 on a shaft 23 which isjournaled in hangers 24.- below the table. Fast on this shaft 23 is adepending arm 25 which is provided at its lower end with a roll 26extending into the race of a cam 27 on a suitably-disposed driven shaft-28. This shaft bears a gear 29 in mesh with agear 30 on the main driveshaft 81 of the machine. The contour of the cam race is such that thearm 25 is oscillated in timed relation to the travel of the carrier;thus rocking the shaft 23 and effecting, through the sector gearing andconnections described, the oscillation of the:

radius arm 17 and, perforce, the simultaneous reciprocation of the twopawls, one movlng in a straight path at the receiving end of the troughand the other in a curved path at the discharging end of the trough) Thepawls in their forward strokes ad Vance the respective trays engagedthereby, and in'their return strokes ride upon the rearward ends of theengaged trays and eninto the underlying ter the next succeeding trays,respectively, and so on. Hence the trays are intermittently pushed, intrain, along the straight and curved portions of the trough by therespective pawls; The timed relation of the travel of the pawls to thator the carrier is such that the leading trays in the curved portion ofthe trough are positively entered into each succeeding holder during thedwell of the latter in its intermittent movement.

I claim 1. In a box-filling machine having an intermittently movablecarrier for match trays, a tray supply trough located laterally andextending longitudinally of the carrier and having a curved deliveryportion of sufi icient radius and length leading to the path of thecarrier, a push pawl adjacent the receiving end of the trough,arociprocating support for said pawl, means for guiding said memberparallel with the body of the trough, a push pawl adjacent the urveddelivery portion of the trough, a radius arm carrying the latter pawland movable in an arc substantially concentric with that of the saiddelivery portion of the trough, a rod flexibly connectingsaid arm withthe said support, and means for oscillating said arm in timed relationto the travel of the carrier.

2. In a box-filling machine having an intermittently movable chain oftray holders, a tray-supply trough located laterally and extendinglongitudinally of the chain and having a curved delivery portion ofsuflicient radius and length leading to the'path 'or' the holders,'apush pawl adjacent the receiving end of the trough, areciprocatingmember supporting said pawl, means for guiding said member parallel withthe body of the trough, a push pawl adjacent the curved delivery portionof the trough, a radius arm carrying the latter pawl and movable in anarc substantiallyconcentric with that of the said delivery portion ofthe trough, a pivot shaft for said arm, a rod flexibly connecting saidarm with the reciprocating member, a rock-shaft, gearing between the twoshafts, and cam connections for actuating the rock-shaft in timedrelation to the travel of the carrier.
